The Influence of DC Component on the Creepage Discharge Paths in Oil-Pressboard Insulation Under AC-DC Combined Voltage

The Influence of DC Component on the Creepage Discharge Paths in Oil-Pressboard Insulation Under AC-DC Combined Voltage

The main dielectric medium in converter transformers is the oil-pressboard. The valve windings of converter transformers are subjected to AC-DC combined voltage. Creepage discharge is a common defect of oil-pressboard insulation. The degree of the oil-immersed pressboard (OIP) damage is directly aff...
